Heart Rate Tracking

Finding the heart on the face

How it works

Did you know that the heart beat leads to optical intensity changes on our skin? These changes are so small that we can’t see them with our eyes but we made sure our algorithms can.

Webcam vs HR monitor

We’ve let a participant play a game. During that time we extracted the heart rate with our system and kept track of the heart rate with a physical heart rate monitor. You can see that our error rate is as little as 1.89%.
